» Keeping Up

I found I never published this post as it was sitting in my drafts few months now — it was written in 13th February, 2010. I’m publishing it without any changes. I learn therefore I am! I’ve just wrote few bits about learning a new technology and after skimming through my Google Reader, I noticed [...]

» An SSH tool to make your life easier

A MySQL user group member saw that I use Poderosa as my ssh-on-Windows tool, and asked why I did not use PuTTY. My response was that I like having tabbed windows and hate having to keep opening another PuTTY program every time I want to open another connection. With Poderosa I can open a new [...]

» Liveblogging: Mentoring: It’s for everyone!

Liveblog of the Professional IT Community Conference session Mentoring: It’s for everyone

Ways to learn:
Audio
Visual
Kinetic (doing it)

Everyone learns differently, but most people learn with some combination of all these three.

However, you can also learn by training [that's the truth, I learned a LOT by writing the book, even things I knew, I ended up needing to research more].

Ways to train:
Explanation
Observation
Demonstration
Questioning (Socratic Method)

What is a mentor?
noun: experienced and trusted adviser. It’s not just someone who teaches, it’s someone who advises.
experienced person in a company, college or schools who trains and counsels new employees or students.

verb: to advise or train (someone, esp. a younger colleague).

A mentorship is a safe place to ask questions.

A mentor is a trainer, but a trainer who also is a professional advisor.

Finding a mentor
Someone…..
- you respect/admire
- works with similar technology
- has a compatible personality
- you have a good rapport with

Being a mentor
- Teach technical skills
- Provide advanced technical/design guidance
- Model and teach professional skills
- Be interested and invested in the [student's] career

» Liveblogging: Tech Women Rule!

I am moderating and liveblogging the Professional IT Community Conference panel called Tech Women Rule! Creative Solutions for being a (or working with a) female technologist.

One point to keep in mind: The goal is not equality for equality’s sake. The goal is to have a diverse range of experience to make your company/project/whatever the best it could be.

That being said, these issues are not just around women; they are about anyone who is “different”, whether it’s race, ethnicity, gender, sexual orientation, cultural.

So what are some of the solutions?

0) Better align expectations with reality. Are you expecting more from someone who is one gender than another? If a woman makes a mistake is it worse because she has to prove herself? Is it worse because she is representative of her gender? If she does something good is the achievement elevated more because of her gender? Either is bad.

1) Respect people for who they are. Everyone deserves respect; if someone is not at your technical level, they still deserve respect.

If someone says something that is completely wrong from a technical perspective, do not assume that they have no idea what they are talking about. It could be that they are the exact case in which that technical scenario is appropriate for them. If they are correct, your attitude will be refreshing and you might learn something. If they are indeed wrong, ask them about a scenario in which their thinking falls apart, or otherwise guide them through learning why what they are saying is wrong.

2) Be nice. Don’t condescend.

3) Be helpful. “RTFM, n00b!” is not helpful, and certainly does not follow rule #2.

4) Don’t do #1-3 for women only. Don’t treat women nicely because they’re women, and be a jerk to men because they’re men. Being helpful is good for anyone, not just women.

5) Cooperate, do not compete. Whether you are co-workers, working together on a software project, or just in a conversation, the game of “one-upping” another is a lot less useful than working together.

6) When hiring or when in an interview, concentrate on skills, not knowledge. “Skills” refers to attributes such as their ability to listen, how judgmental they are about a legacy system, whether they are open to new ideas, whether they disdain anything that is not cutting edge, and even technical skills such as thinking patterns, research patterns, algorithms, etc.

If someone says “I don’t know” in an interview, ask them “how would you go about figuring it out?” If someone says “I think it’s x and y” ask “how would you confirm/test that?” If a backup failed, do they start the backup over or do they try to figure out why it failed?

Are they thorough? Do they follow through? It is a lot easier to teach knowledge than it is to teach something like “debugging skills”.

7) Specifically encourage people to speak up. Train yourself to NOTICE when folks are not speaking up, and ask them if they have any suggestions or ideas.

8) If you are running an IT conference, specifically ask qualified women you know to speak, not about “women in IT”. If you hear of an IT conference, tell specific women you know that you think they would be a great speaker. Get women to speak at local user groups to get practice in a less intimidating space.

» Liveblogging: Senior Skills: Sysadmin Patterns

The Beacon Pattern:
- This is a “Get out of the business” pattern
- Identify an oft-occurring and annoying task
- Automate and document it to the point of being able to hand it off to someone far less technical

Example:
- System admins were being put in charge of scheduling rooms in the building
- They wrote a PHP web application to help them automate the task
- They refined the app, documented how to use it, and handed it off to a secretary
- They have to maintain the app, but it’s far less work.

The Community Pattern:

- Prior to launch of a new service, create user documentation for it.
- Point a few early adopters at the documentation and see if they can use the service with minimal support
- Use feedback to improve documentation, and the service
- Upon launch, create a mailing list, forum, IRC channel, or Jabber chat room and ask early adopters to help test it out.
- Upon launch, your early adopters are the community, and they’ll tell new users to use the tools you’ve provided instead of calling you.

Example:
- A beowulf cluster for an academic department
- Documented like crazy, early adopters were given early access to the cluster (demand was high)
- Crated a mailing list, early adopters were added to it with their consent, functionality was tested with them.
- Email announcing launch mentioned the early adopters in a ‘thank you’ secion, and linked them to their mailing list.

The DRY pattern
DRY = Don’t repeat yourself
Identify duplicate code in your automation scripts
Put subroutines that exist in an include file, and include them in your scripts.

Example:
- “sysadmin library”
- /var/lib/adm/.*pl
- Elapsed time and # of lines to script a task for which the library was useful plunged dramatically
– new tasks were thought up that were not considered before but were obvious now (ie, users that want to change their username)
– migrating to new services became much easier

The Chameleon Pattern
- Identify commonalities among your services
- Leverage those to create “Chameleon” servers that can be re-purposed on the fly
- Abstract as much of this away from the physical hardware
- Doesn’t need to involve virtualization, though it’s awfully handy if you can do it that way.
[this one is a bit harder to do with MySQL config files]

Example:
[puppet/cfengine were mentioned...]
ldapconfig.py – more than a script: a methodology

- But isn’t installing packages you don’t need bad? Depends on the package….ie, gcc is bad for enterprise

“Junior annoynances”

Terminal issues

Junior:
open terminal, login to machine1
think issue is with machine2, talks to machine1.
log out of machine1
log into machine2

Senior:
opens 2 terminals each of machine1 and machine2 to start

Junior:
networking issue ticket arrives
logs into server
runs tcpdump

Senior:
networking issue ticket arrives
logs into server
looks at logs

“Fix” vs. “Solution” ie “taking orders”
Junior will try fix a problem, senior will try to figure out what the problem is. ie, “I need a samba directory mounted under an NFS mount” a junior admin will try to do exactly that, a senior admin will ask “what are you trying to do with that?” because maybe all they need is a symlink.

Fanboyism
Signs you might be a fanboy:
- Disparaging users of latest stable release of $THING for not using the nightly (unstable) build which fixes more issues
- Creating false/invalid comparisons based on popular opinion instead of experience/facts
- Going against internal standards, breaking environmental consistency, to use $THING instead of $STANDARD (but this is also how disruptive technology works)
- Being in complete denial that most technology at some point or another stinks.
- Evaluating solutions based on “I like” instead of “we need” and “this does”.

» Liveblogging: Seeking Senior and Beyond

I am attending the Professional IT Community Conference – it is put on by the League of Professional System Administrators (LOPSA), and is a 2-day community conference. There are technical and “soft” topics — the audience is system administrators. While technical topics such as Essential IPv6 for Linux Administrators are not essential for my job, many of the “soft” topics are directly applicable and relevant to DBAs too. (I am speaking on How to Stop Hating MySQL tomorrow.)

So I am in Seeking Senior and Beyond: The Tech Skills That Get You Promoted. The first part talks about the definition of what it means to be senior, and it completely relates to DBA work:
works and plays well with other
understands “ability”
leads by example
lives to share knowledge
understands “Service”
thoughtful of the consequences of their actions
understands projects
cool under pressure

Good Qualities:
confident
empathetic
humane
personal
forthright
respectful
thorough

Bad Qualities:
disrespective
insensitive
incompetent
[my own addition - no follow through, lack of attention to detail]

The Dice/Monster Factor – what do job sites see as important for a senior position?

They back up the SAGE 5-year experience requirement
Ability to code in newer languages (Ruby/Python) is more prevalent (perhaps cloud-induced?)

The cloud allows sysadmin tasks to be done by anyone…..so developers can do sysadmin work, and you end up seeing schizophrenic job descriptions such as

About the 5-year requirement:
- Senior after 5 years? What happens after 10 years?
- Most electricians, by comparison, haven’t even completed an *apprenticeship* in 5 years.

Senior Administrators Code
- not just 20-line shell scripts
- coding skills are part of a sysadmin skill
- ability to code competently *is* a factor that separates juniors from seniors
- hiring managers expect senior admins to be competent coders.

If you are not a coder
- pick a language, any language
- do not listen to fans, find one that fits how you think, they all work…..
- …that being said, some languages are more practical than others (ie, .NET probably is not the best language to learn if you are a Unix sysadmin).

Popular admin languages:
- Perl: classic admin scripting language. Learn at least the basics, because you will see it in any environment that has been around for more than 5 years.

- Ruby: object-oriented language for people who mostly like Perl (except for its OO implementation)

- Python: object-oriented language for people who mostly hate Perl, objects or no objects. For example, you don’t have to create a String object to send an output.

But what if you do not have time to learn how to program?

- senior admins are better at managing their time than junior admins, so perhaps managing time
- time management means you’ll have more time to do things, it doesn’t mean all work work work.
- Read Time Management for System Administrators – there is Google Video of a presentation by the author, Tom Limoncelli.

Consider “The Cloud”
- starting to use developer APIs to perform sysadmin tasks, so learning programming is good.
- still growing, could supplant large portions of datacenter real estate
- a coder with sysadmin knowledge: Good
- a sysadmin with coding knowledge: Good
- a coder without sysadmin knowledge: OK
- a sysadmin with no coding interest/experience: Tough place to be in

Senior Admins Have Problems Too
Many don’t document or share knowledge
Maany don’t do a good job keeping up with their craft
Cannot always be highlighted as an example of how to deal with clients
Often reinvent the wheel – also usually there is no repository
Often don’t progress beyond the “senior admin” role

….on the other hand…..
cynicism can be good…..

Advice:
learn from the good traits
observe how others respond to their bad traits
think about how you might improve upon that
strive to work and play well with others, even if you don’t have a mentor for good/bad examples.

Now he’s going into talking about Patterns in System Administration….

» Blogrotate #3: The Weekly Roundup of News for System Administrators

Welcome to volume 3 of Blogrotate. This is a short one this week, which is mostly dominated by the release of Windows 7. I have not had a chance to use it as yet but intend to give it a once over as soon as I get a chance. So, without further ado, on to the roundup.

Operating Systems

The big story this week was obviously the release of Microsoft’s Windows 7.  There are a number of good articles we’ve seen that cover different aspects of the release.  Some of our favourites are below.

Emil Protalinski over at Ars Technica has a look at the things you should know about Windows 7 in his article Windows 7 is here including pricing information, editions available and upgrade vs. fresh install.

Andrew Binstock at InfoWorld has an interesting look at the changes made to the Windows 7 kernel, specifically with regards to multithreaded performance in Windows 7 on multicore: How much faster.

Do you want to know if your system will be able to run Windows 7? See  Emil Protalinski’s article Are you Windows 7 compatible for more.

And on an amusing note, Apple premiered a new Mac ad last night (the same day Windows 7 was released) poking fun at Windows’ broken promises of the past.  This is a hoot, even if you love your Windows.  Careful if you have web filtering, some comments are NSFW.

Canonical and IBM team up on Ubuntu-based Win 7 alternative is an interesting article by Ryan Paul about an attempt to divert companies from using Windows.  The idea is that using a free OS like Ubuntu, and IBM’s Client for Smart Work can allow a company to extend its IT dollar by reducing licensing costs and keeping their old hardware, on which Ubuntu will run just fine.

Happy 5th anniversary to Ubuntu Linux. 5 years later, 5 ways that Ubuntu has made Linux more human is a look at some of the ways Ubuntu has impacted the OS world.

The H has posted an announcement that states CentOS 5.4 released to the public. We’ve been waiting for this since RedHat 5.4 was released in September. Time to upgrade your servers. The official release announcement can be found on the CentOS-Announce mailing list archive post Release for CentOS-5.4 i386 and x86_64.

Networking

Better wifi for mobile computers? Slashdot has an interesting post about a town in Virgina that has launched the first ever network employing unused frequencies, or white space, from the TV spectrum to run the network. See First Public White-Space Network Is Alive and the links therein for more.

Hardware

Slashdot has a post about NCSU’s Fingernail-Size Chip Can Hold 1TB of data. This is really something, but I can barely afford a 16GB now, these will cost a fortune.

Operating Systems (again?)

Last but certainly not least, be on the lookout for the release of Ubuntu 9.10 Karmic Koala which is slated for release on October 29. I’ve mentioned previously that I have been running the beta of Kubuntu for a couple of weeks now and I have to say, even with the beta bugs, I like what I see. More about that next week.

» First Impressions of Kubuntu 9.04

I said I would follow up. Who knew I actually would?

I love my new PC. It’s been a few years since I did a build for myself, so I took my time lovingly feeling every piece for the tactile joy of it, and completely ignoring any printed material that came with the parts. Well, I did read the bit about the front panel connectors, that one is kind of a must when it’s not printed on the board.

For the record it consists of an ASUS M3A78-EM with an AMD Athlon 64X2 7750 Black Box. I was on a budget so I could not go for the quad core as yet, so I made sure I got a mobo that would stand some upgrades when the price-point drops. Check out the ports on the mobo, it has everything. Check out the cache on the CPU (1MB L2, 2MB L3). I am sticking with the on-board video for now; I prefer NVidia to ATI, but for the moment it will do. It fit the price.

All of that has nothing to do with Kubuntu. Since I got the parts together late, I did not have as much time to play as I would have liked, but I do know that it boots very quickly. I will time it this weekend, but it was around 15 seconds from GRUB to KDM. I did some installs of apps that were not shipped with the default desktop, such as Firefox, mplayer, fglrx, and a few other choice bits I like (which I will mention by name in a follow-up). I was fairly impressed so far.

Now for the bad news. From the get-go KDE 4.2 let me down. When 4.0 arrived with Kubuntu 8.10, I tried it for a day or two, and was very unimpressed. This time I thought it must have had some improvements, it’s now two minor revisions beyond the dreaded .0 version. While it is slightly more stable, within minutes I had had my first crash on the panel. I had several more, not hardware-related. Now these could be the fault of the applet developers and not KDE itself, but it certainly soured my first look. I will probably nuke this install and reinstall with the KDE3 remix over the weekend.

One I got fglrx running, I just had to install Nexuiz. I did buy faster hardware and lots more RAM, how else was I to see it in action? I gotta say it ran smoothly. So what if I can’t hit anything or bunny-hop my way out of danger.

Till next time, keep your clock multiplier high and your temperature low.

» End of School with Linux; Ubuntu 9.04 Released

Hi folks. I am back for the second in what will eventually be a long line of infrequent updates. Did you miss me?

End of School with Linux

OCLUG (The Ottawa Canada Linux Users Group) is putting on an event called—you guessed it—End of School with Linux. This is happening on April 28, 2009 starting at 11am at the University of Ottawa in the SITE building, room C0136. The purpose of the event is to help people with their Linux systems, install Linux, fix issues, and just generally help out in the community. Your humble blogger will be there, manning the booth from 1200-1600, so come on down. And tell a friend, too.

More details can be found at the CSSA’s page. Click here for a map of the campus.

Also check out the OCLUG home page.

Ubuntu 9.04 Released

Ubuntu 9.04 was released today. I have not yet looked at any reviews of the release candidates, but I am on my way out to pick up some new hardware on which to install it tonight.

If you were not on the sites downloading it early today you may have to wait, as most mirrors are very busy. If you have a newsgroup account then check out alt.binaries.cd.images—the ISO for 32-bit and 64-bit are there in both desktop and server flavours. For some reason, the Kubuntu and Edubuntu releases are not in the newsgroups, but you can always install the meta-packages after installing from the main ubuntu dist using apt-get install kubuntu.

Over the next few days I will be doing an install of the 64-bit version on my hefty(ish) new system, and a 32-bit install on my sorely-outdated laptop. I will post results.

Don’t forget to check out the Ubuntu web site.

One final thought

Did I mention I am going to get new hardware tonight? It’s been years! I am blogging and doing work, but all I hear in my head is “EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE”! It’s a wonderful kind of feeling.

Till next time.

» Log Buffer #128: a Carnival of the Vanities for DBAs

Welcome to the 128th edition of Log Buffer, the weekly review of database blogs.

Let’s begin with some PostgreSQL blogs. Jignesh Shah shares his recipe for making a PostgreSQL 8.3 appliance based on OpenSolaris using VirtualBox. While we’re on appliances, Dave Page shows off PostgreSQL management on the iPhone with an application he himself wrote. Stealth DBA for the bus-rise home.

On Database Soup, Josh Berkus has been finding useless indexes. He begins, “I’d say, in general, that you can’t have really well-chosen indexes without the help of a performance expert. However, anyone can improve their use of indexes in PostgreSQL fairly easily using a few system tools … and a little improvement is all that a lot of users need.” And it’s what Josh offers.

Sometimes a DBA is asked to make something real purty-like, contrary to his or her nature though that may be. On the Postgres OnLine Journal, Leo Hsu and Regina Obe offer some help with the first of a series on Fusion charts and PostgreSQL. (”Fusion Charts . . . is a flash-based charting product that makes beautiful flash charts.”)

And now—hey what’s MySQL maven Baron Schwartz doing with a Postgres post on xaprb? He’s asking, what are your favorite PostgreSQL performance resources?

Maybe he’s considering crossing the floor out of weariness with all the contention in the MySQL world? Can’t say I blame him. Lately, the conversation in the MySQL ’sphere has been dominated by non-technical talk of the pluses and minuses of 5.1, of forking, community vs. enterprise, and so on. This week was no exception.

The week began with Jay Pipes’s advice to MySQL: “Drop the current roadmap . . . Forget Windows for now . . . Clean up the abysmal messiness of the code base . . .” It’s strong stuff and worth a read.

Lukas Kahwe Smith followed with his advice to the database division at Sun, purveyor or patron now of MySQL, Drizzle, and PostgreSQL.

Jeremy Zawodny surveyed this new MySQL landscape, full as it now is of patches, forks, and Drizzle, and liked what he saw.

Speaking of which, the MySQL Performance Blog announced the Percona XtraDB Storage Engine: a drop-in replacement for standard InnoDB.

Ronald Bradford got some unexpected results while looking into the size of memory tables. Can you help Ronald out?

On High Availability MySQL, Mark Callaghan showed us how to make MySQL faster in one hour. Nice stuff. And real purty charts, too.

Let’s see what happened in SQL Server now. Kalen Delany opined that there is no such thing as a SQL Server, and she’s not the only one with an opinion on this (one would think) straight-forward matter.

Lichi Shea asserted that there is a limit to set-based solutions: “After all, some procedural solutions are not so bad!  . . .  Now, it’s time for me to dodge the set-based solution crowd.”

Lots of thoughtful comment on that one, and a blog response from Ward Pond, who says that Linchi Shea makes an interesting point about hints, vis-a-vis the set-based and procedural paradigms.

The Data Management Journal looked into extracting numbers with SQL Server: “We all have perfectly normalized tables, with perfectly scrubbed data, right? I wish! Sometimes we are stuck with dirty data in legacy applications. What’s worse is that we are sometimes expected to do interesting things with dirty data. In this blog, I will show you how to extract a number from a varchar column that contains letters and numbers.”

TJay Belt published his reflection, Cloud Computing and me. Like many DBAs, TJay has some thoughts on how the advent of “The Cloud” is going to affect databases and database administration.

Moving into things Oracle, Chen Shapira was thinking about a musical analogy for the DBA. Their not “rockstar programmers” or “jazz programmers”, says Chen. But I won’t give away her conclusion—click on.

Chet Justice, the Oracle Nerd, was pursuing ontology too in the second part of his Application Developers vs. Database Developers. (I wonder if it’s generally true that apps developers have such terrible manners.)

Gary Myers responded, “Oraclenerd has opened that can of worms about OO, ORMs and Databases,” in his item, The Certainty Bottleneck (and ORMs).

On An Expert’s Guide to Database Solutions, James Koopman suggested, maybe it’s time to extend the DBA’s realm of influence, using tools like Spotlight on Oracle.

Or perhaps with other tools, such as TOra? Here on the Pythian Blog, Brad Hudson posted his howto, Installing TOra with Oracle support on Ubuntu 8.04LTS (Hardy Heron).

One last important bit of news from this week—Thomas LaRock, AKA SQLBatman, is America’s Most Exciting DBA.

Until next time, Happy Holidays to all our readers!

» Liveblogging: Automated System Management

Usenix 2008 - Automated System Management, by Æleen Frisch of Exponential Consulting (and numerous books)

What is automation?

generic [perl|shell] scripts with cron,at

Problem: overlap of effort

So folks developed automation systems. General automation tools are around:

cfengine, puppet, cfg2

These are general — files, directories, etc. Don’t need to use chmod and chown and underlying commands.

However, they don’t really survive reboots well. For that, we tend to use tools more towards jumpstart, kickstart.

Monitoring with Nagios, related tools are rrd-tools such as cacti, cricket, munin, “or any of 8,000 others.” Automating ideas like iostat.

Nessus is a security testing tool.

homegrown, general, performance related, also automated backups — bakula, amanda, legato.

What do you want automated?

“Coffee machines”.

A lot of unsolved problems are human interaction.

Other problems solved — using remote power management.

Inventory management is another issue. HP OpenView is one, but Frisch says folks are not happy with it. You can pay for high-end monitoring systems.

A question came up about an inventory of users on systems. LDAP or NIS or Active Directory is the traditional solution where there are no local accounts. There’s authentication and then authorization, and the automated tools usually have authentication information but not authorization information. (You can handle it, but making groups on these tools is usually painful.) Authorization is usually handled either locally or as “if you’re authenticated you’re authorized”.

We talked about how to power down 500 machines when the air conditioning goes out, or when the power is going down. Combinations of temperature probes, “wake-on-lan”, remote power on and off were discussed.

What do people use to automate installs and configuration on Windows? For installation, the Windows native tools are great. It was noted that efs works better on Windows.

Anyone using Splunk with Windows? One answer — it works OK, there are some daemon tools to convert Windows Event Log to syslog.

Splunk came up as a topic of discussion, how it’s a great log management software and solves a problem we’ve had for decades — how to deal with logs. Frisch says, “Splunk is the most promising thing out there.”

Record keeping of time was brought up, as well as time management. Basically what we do at Pythian, so I explained how we do things. Other folks brought up ticketing systems as well. Jira and RT (Request Tracker) and OTRS (Open Ticket Request System) were brought up as well.

Also for change management, some folks use ClearCase (not open source), and others use rancid, others use Trac or bugzilla + change management system like subversion. Jira was recommended as a product that does both (with an add-on).

Use DHCP to help automate IP assigning. rsync is your friend too.

(it occurs to me that a dishwasher is an interesting problem; why do we have a dishwasher instead of just having a sink/dishwasher hybrid? Similarly, a hamper that does laundry for you when it’s full.)
